LAWNS OF UFA (BASHKORTOSTAN REPUBLIC)

Abstract

The present work reflects the results of studying two types of lawns - seeded and rolled. More than 100 geobotanical descriptions of lawns were performed in all areas of the settlement zone of the city. The conducted research showed that vegetation of lawns of Ufa quite poor and includes only 4 associations - LeontodontoPoetum pratensis, Inulo britannicae-Trifolietum repentis, Poo pratensis-Plantaginetum majoris, Lolietum perennis which are carried to the union of Cynosurion cristati of the class Molinio-Arrhenatheretea. The vegetation of rolled and seeded lawns does not differ significantly. It is noted that the most represented species of the three families are Asteraceae ( Achillea millefolium, Taraxacum officinale , etc.), Poaceae ( Poa pratensis, Festuca rubra, etc.) and Fabaceae ( Amoria repens, Medicago lupulina etс.). As part of the studied lawns, we identified foreign ( Lactuca serriola, Berteroa incana , etc.) and aggressive invasive ( Erigeron annuus, Hordeum jubatum, Solidago canadensis ) plant species. The change in the composition of lawn communities compared to the data of the 1980s is associated with the use of modern grass mixtures containing other species of cereals.
